A solid-liquid-gas three-phase complete equation of state of aluminum

摘要: 基于GRAY模型建立了金属铝的固液气三相完全物态方程，并与等温压缩线、Hugoniot线、熔化线以及零压热力学函数的实验结果进行对比，表明本物态方程可合理描述金属铝在宽广热力学空间的热力学状态。

Abstract: Based on the GRAY equation of state (EOS), we establish a solid-liquid-gas three-phase complete EOS, and compare it with the experimental isothermal compression data, Hugoniot data, melting data and thermodynamic functions under ambient pressure. It is indicated that the EOS in this paper can describe reasonably the thermodynamic state of aluminum in a wide region.
